FIELD OF THE INVENTION

The present invention relates to retaining frames, in particular to aretaining frame of a display, wherein the angle of the display can beadjusted conveniently and rapidly.

BACKGROUND OF THE INVENTION

The prior art retaining frame for a display has a supporting seat havingfour cambered sliding grooves which are annular and spaced with oneanother for locking four studs of a swingable seat. Thus four nuts lockthe structures so that the supporting seat is retained to the swingingseat. However when the display moves so that the first arm and thesecond arm of the retaining seat swing, by the weight of the display andthe non-uniform force, the supporting seat will slide along the slidinggrooves so that the display will shift aside. Especially the larger thedisplay, the great the shift. If it is desired to adjust the display tothe horizontal position in above display retaining frame, the displaymust be detached from the supporting seat, and then the nuts arereleased. After the supporting seat is adjusted to horizontal positions,the nuts are locked again. The adjustment is tedious and the detachingand assembling works must be done by two persons. However the weight ofthe display and the non-uniform force, the supporting seat will slidealong the sliding grooves so that the display will shift aside and thusit makes difficult to users.

A retaining seat 1 has a seat body 10, a first arm 11 and a second arm12. The seat body 10 can be fixed to a wall. Two ends of the first arm11 have a first pivot portion 110 and a second pivot portion 111,respectively. The first pivot portion 110 is connected to the seat body10 so that the first arm 11 is swingable horizontally along the seatbody 10. Two ends of the second arm 12 have a first pivot portion 120and a second pivot portion 121, respectively. The first pivot portion120 of the second arm 12 is connected to the second pivot portion 111 ofthe first arm 11 so that the second arm 12 is swingable horizontallyalong second pivot portion 111 of the first arm 11. The second pivotportion 121 of the second arm 12 has a longitudinal and axiallyrotatable stand rod 13. The stand rod 13 has a penetrating via hole 130.An outer wall of the stand rod 13 is a retaining plane 131 at aperiphery of the via hole 130.

A supporting seat 2 has a receiving surface 20, an embedding groove 21and a penetrating hole 22. The receiving surface 20 has a concavecambered surface. The embedding groove 21 is at a backside of thereceiving surface 20 for receiving the stand rod 13. The penetratinghole 22 penetrates through the receiving surface 20 to the embeddinggroove 21 at a central portion thereof.

The swingable sheet 3 is punched with a cambered connecting portion 30.A front surface of the connecting portion 30 has a concave camberedsurface 31 and a back surface thereof has a convex cambered surface 32which resists against the receiving surface 20 of the supporting seat 2.A center of the connecting portion 30 has a penetrating long hole 33.

The tighten sheet 4 has a convex portion 40 and a contact portion 41.The convex portion 40 is a convex cambered surface which protrudestoward a direction far away from the connecting portion 30. The contactportion 41 is integrally formed around a periphery of the convex portion40 and has protruding outer sides protruding to a direction like that ofthe convex portion 40. The contact portion 41 is adhered to the concavecambered surface 31. A center of the convex portion 40 has a penetratingthrough hole 42.

An adjusting set 5 has a stud 50, a pad 51, an adjusting nut 52 and astop nut 53. The stud 50 has a head 500 and a threaded post 501. Thethreaded post 501 penetrates through the through hole 42 of the tightensheet 4, the long hole 33 of the swingable sheet 3, the penetrating hole22 of the supporting seat 2 and the via hole 130 of the stand rod 13 sothat the head 500 presses upon the convex portion 40 of the tightensheet 4 and one end portion of the threaded post 501 protrudes out oneside of the stand rod 13. The pad 51 encloses the threaded post 501 toadhere to the retaining plane 131 of the stand rod 13. The adjusting nut52 locks the threaded post 501 and stop at the outer side of theadjusting nut 52 for preventing the adjusting nut 52 from releasing.

The cover 6 serves to cover the supporting seat 2 and the stand rod 13.

The supporting base 7 has one base body 70 and two frame sheets 71. Thebase body 70 is combined to the swingable sheet 3. The two frame sheets71 are longitudinally installed to the base body 70 and is capable tomove horizontally along the base body 70 or positioning thereon. Eachframe sheet 71 has a plurality of retaining holes for locking a display8.

Referring to FIG. 6, by movement of the first arm 11 and second arm 12,the distance between the display 8 and a wall is adjustable.

Referring to FIGS. 5 and 7, the connecting portion 30 of the swingablesheet 3 is matched to the receiving surface 20 of the supporting seat 2and the tighten sheet 4 is combined to the adjusting set 5 so that theshifts in the horizontal direction and vertical direction areadjustable.

Referring to FIG. 8, by the connecting portion 30 of the swingable sheet3 matched to the receiving surface 20 of the supporting seat 2, and thetighten sheet 4 combined to the adjusting set 5, and the stud 50 toinsert into the long hole 33 of the connecting portion 30 of theswingable sheet 3, the elevational angle of the display 8 is adjustable.Especially, tightening or releasing the adjusting nut 52, the tightensheet 4, swingable sheet 3 and the supporting seat 2 are adjustable totighten or release. Thus, the friction forces between the contactportion 41 of the tighten sheet 4 and the concave cambered surface 31 ofthe connecting portion 30 and the friction force between the convexcambered surface 32 and the receiving surface 20 are also adjustable.

Referring to FIG. 9, another embodiment of the present invention isillustrated. In this embodiment, the swingable sheet 3 has a pluralityof retaining holes 34 for locking the display 8.

In this embodiment, the connecting portion 30 of the swingable sheet 3is slidable along the receiving surface 20 of the supporting seat 2.Furthermore, the receiving surface 20 and the connecting portion 30 havecambered surfaces so that the user can move the display 8 to a desireposition. By the contact between the contact portion 41 of the tightensheet 4 and the concave cambered surface 31 of the connecting portion30, and a larger contact area of the convex cambered surface 32 of theconnecting portion 30, a large friction force is generated so that itcan suffer from a larger friction force from the swinging of the display8. No screw or stud is necessary to be detached, while the display 8 canswing or be positioned to a desired angle. Especially, by adjusting thefriction force using the adjusting set 5, the swingable sheet 3 cansupport a display 8 of any weight. Thus the user can adjust the angle ofthe display 8 conveniently and rapidly.
